About the client

SpaceNest — a leading domestic pioneer driving space sharing.

SpaceNest, with the mission of “bringing new value to unused spaces,” runs a marketplace business for renting meeting rooms, event spaces, photo studios and more by the hour, connecting hosts and guests nationwide.

To make idle spaces productive and let people quickly find the right place for their needs, we launched a mobile app from scratch that handles everything from map search to booking and chat.

CHALLENGE
The design challenge to solve

The four structural requirements space sharing demanded.

None of these were mere feature additions — each was a business requirement tied directly to host occupancy, guest discoverability and transaction trust. Building from scratch, we needed a design that made all of them work at once.

Enable idle spaces to be rented out
Without the means,spaces stay idle emerges.
Let users instantly find a place that fits their purpose
When it's hard to find,Usage opportunities are missed.
Centralize bookings and inquiries
When phone and email are scattered,Missed responses occur.
Enable safe, worry-free transactions
When communication is opaque,The barrier to use rises.

ARCHITECTURE
The architecture we built together

Turning the lend-and-rent experience into an “unstoppable platform” across four domains.

We built four domains — map search, booking, chat and review — from scratch in-house, combining an Express API, native apps and an admin CMS. It's the launch of a new space-sharing platform where hosts and guests connect with confidence in the app.
